Bentley Continental GT3 grows wings to conquer the Pikes Peak Hill Climb

Apparently, this is a Bentley. That may not be obvious at first glance on account of the … everything, but this winged beast does have a Bentley logo on it. You see, Bentley is headed on back to Pikes Peak for a third (and final) time. The companyÂ’s first two visits saw the production SUV record achieved with the Bentayga W12 and the outright production car record taken with the Continental GT. This time, Bentley is targeting the “Time Attack 1” record, and the Continental GT3 Pikes Peak is its steed of choice. Leading the car's superlative features is what Bentley claims to be “the biggest rear wing ever fitted to a Bentley.” We heartily approve. The aerodynamic package is fully in vogue with other cars built specifically for Pikes Peak. Maximum downforce is generated with the huge wing, a gigantic diffuser, two-plane splitter and aggressive dive planes. ItÂ’s more track rat than elegant race car with the numerous scoops and venting throughout. The exhaust cutouts just aft of the front wheels complete the hooligan package. This Continental may have Bentley lights on it, but the similarities between it and the road car donÂ’t go much further. Details about the engine are limited, but Bentley says itÂ’s a 4.0-liter turbocharged V8 racing engine, not a production V8 or W12. Modifications were made to make it more powerful for this Pikes Peak run, but Bentley also made adjustments for the fuel it will be running in the car. Instead of running this Continental on race fuel, itÂ’s going to be using biofuel-based gasoline. WeÂ’ve heard Porsche make waves about the potential of greener biofuels helping to drastically reduce emissions, and now Bentley is making some noise about the tech, too. In coordination with Porsche (all in the same VW Group house), Bentley is researching how it could use biofuels and “e-fuels” to potentially power both past and future Bentley cars. As of today, Bentley is saying that using these fuels could result in greenhouse gas emissions reductions of up to 85%. Put simply, thatÂ’s huge, if it can be made to work at a large scale. Bentley expressly states that this research into biofuels doesnÂ’t affect its plan to become an electric-only automaker by 2030. Instead, Bentley sees it as a way to allow the brandÂ’s past and current gasoline-powered vehicles to be driven far into the future — just over 80% of all Bentleys ever built are still on the road, according to BentleyÂ’s internal tracking.

Bentley builds its final 6.75-liter V8, ending a 61-year production run

Bentley has just finished its very last 6.75-liter V8. While engines come and go, this is significant because Bentley has been building this engine, known as the L-series, for 61 years. This final engine will go in the 30th and last Bentley Mulsanne, a 6.75 Edition by Mulliner, marking the end of the flagship sedan. The L-series engine was first introduced in 1959, and according to Bentley, it was developed in order to develop more power than its existing inline-six without adding weight or taking up more space. The engine in fact weighed 30 pounds less than the six-cylinder, and it made about 180 horsepower. That original engine "only" had 6.2-liters of displacement, and it wasn't until 1971 that it would reach 6.75 liters thanks to increased stroke. This final version of the engine is significantly different from its fuel injection to its twin-turbochargers, but is based on the same design. And with 530 horsepower and 811 pound-feet of torque, it's the most powerful iteration of the engine. At 61 years, the Bentley engine is arguably the V8 with the longest production run. While the first-generation Chevy small block V8 was introduced earlier for the 1955 model year and is still built in crate engine form, GM stopped using it in production cars in 2002. Far fewer Bentley engines were built, though, with a total over 36,000, as opposed to the millions of Chevy small blocks in the world. Of course, volume is sort of the antithesis of what makes a Bentley a Bentley. With the 6.75-liter engine out of production, all of Bentley's engines are derived from VW Group engines, from its W12 to the plug-in hybrid V6. Related Video:    

40+ cars that barely avoid the gas guzzler tax

The Gas Guzzler schedule, with mpg ratings and charges that haven't changed since 1991, lays out which fuel-swillers owe what to Uncle Sam.
I started thinking about the "Gas Guzzler Tax" - considerably less well known as The Energy Tax Act of 1978 - when I was driving Dodge's new Challenger SRT Hellcat last week. Unsurprisingly for a car that can burn 1.5 gallons of gas per minute at max tilt, theoretically able to empty a full tank of premium in about 13 minutes, the Hellcat will be subject to the Gas Guzzler Tax schedule when it goes on sale.
